Marriage and proposal

Assalamu alaikum,Respected Mufti Sahab,I am a male and Insha Allah I am planning to get married very soon.So I want to ask a few questions relating to it.1.What I should be looking in a prospective girl/wife? Can one appoint a middle person (we call Motasha) who brings different kinds of proposals and then when every thing is final from both the girl and the boys side and when nikah is done or finalised then she/he charges some amount say Rs 10,00/- each from both the boy and the girl side.So I want to ask whether appointing these kind of person whether male or female and then paying then for their service ok or it is not allowed in islam.2 If the boy or the girl’s family members or the boy and the girl want photograph to see,should one provide it or should one go personally of course with the family members with them and see the girl or the boy in front of them. The problem is that if the girl side do not want to make the girl and the boy see each other as they might raise a point that my daughter is not a cow that everyone may come and see and if one does not like they will go away and then another proposal which comes later they might request to see the girl and if they don’t like then they will also go away in this way the girl will also be demoralised mentally and also every now and then proposal will come and go just by seeing the girl and it will become a toy for people.So this is the reason why they prefer giving photographs. What to do in this scenario?3.Can one ask for bio-data of the boy or the girl and if yes then how can one know whether what is written in the bio-data is 100% true or correct. How to determine that?4. what question should one ask the girl or the boy if one is allowed to see each other and talk to each other obviously in the presence of the family members to to know his/her character,chastity,righteousness etc.May Allah bless you with his Rahmat and please make dua for me for a pious wife which is good for me in all worlds.Jazzak Allah!

1. Paid middle man system is NOT good. Must avoid.
2. No photo exchange.
3. Yes.
4. Purpose/ goal/ objective in life to be determined. Stability, salary, questioned. Salaat regularity, which group does one being to?
